UNITED STATES WVILLIAM UOPPAGE, OF TERRE HAUTE, INDIANA, ASSIGNOR OF ONE-HALF TO WILLIAM H. LARIMER, OF SAME PLACE.

CORD-HOLDER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 515,113, dated February 20, 1894.

Application filed September 21, 1893. Serial No. 486,071. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM COPPAGE, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Cord- Holder for Grain-Binders, of which the following is a specification.

My invention relates to an improvement in the clamping-shoe of the cord-holder commonly used in the well known Appleby type of grain-binders. As heretofore constructed, the clamping-shoe, which holds the ends of the bight formed in the cord and inclosing the bundle of grain, has consisted of a fiat plate having in its edge a circular grooved recess adapted to receive and fit the edge of the notched cord-carryingwheel, the edges of said grooved plate which over-lap the notched wheel operating to clamp the ends of the cord simultaneously and equally against the bottom of the notches in the wheel.

It is found in practice that. the cord used for binding grain is not of uniform diameter, but is full of inequalities, and that when the ends in the bight of the cord which come together are of unequal diameter but one of them will be held firmly by the clampingshoe, preparatory to tying the knot.

The object of my improvement is, to provide a clamping-shoe adapted to hold the ends of the bight in the cord together and simultaneously but with an independent pressure on each.

The accompanying drawings illustrate my invention.

Figure 1, represents a plan of one side of my cord-holding device. Fig. 2, represents a plan of the opposite side; and Fig. 3, an edge vlew.

In the drawings, 2, indicates a rigid arm forming a part of the frame of the knotting mechanism of the grain-binder. The well known notched disk or cord-carrying wheel, 3, is pivoted to said arm so as to revolve thereon. The hub of disk, 3, is provided with ratchet teeth, 4, which are engaged bya pawl, 5, which is pivoted to a lever, 6, which is actuated intermittently by connecting mechanism, (not shown) connecting the lever with a moving part of the grain-binder. Pivoted to arm, 2, at, 7, is a flat plate, 8, forming part of the clamping-shoe and having in one edge a circular notch, 9, which is recessed on one side as at, 10, so as to receive the edge of disk, 3, and to form a flange, 11, which over-laps one side of the disk. Upon the opposite side of plate, 8, are mounted a pair of thin plates, 12, and, 13, which are arranged to over-lap the side of disk, 3, and are held with a yielding force against the side of the disk by means of springs, 14, and, 15.

The arrangement of the parts is such that when the bight in the cord, 16, has been formed, the two ends of the bight resting in one of the notches of the disk, 3, are carried by the partial rotation of the disk between the portions of plates,12, and, 13, which overlap the disk, and the side of the disk, until the notch carrying the cord comes opposite the joint between the plates, 12, and, 13. In this position each of the ends of the cord forming the bight is independently held by the pressure against the face of the disk, which is provided with corrugations, 17, which insure a firm hold upon the cord. By this construction each end of the bight is held independently, and therefore, firmly, regardless of the inequalities thereof.

I claim as my invention v1. In a cord-holder for grain-binders, the combination of the pivoted notched cordcarrying disk, and the clamping-shoe consisting of the notched plate adapted to embrace the edge of the disk and provided with a flange which over-laps one side of the disk, the pair of plates mounted on said notched plate opposite said flange, and the springs arranged to hold said plates with a yielding force against the side of the disk, all substantially as and for the purpose set forth.

2. In a cord-holder for grain-binders, the combination of a notched rotatable cord-carrier, and a pair of spring-controlled clamping plates arranged adjacent to each other and adapted to press against one side of said cordcarrier, so as to clamp the two ends of the bight of the cord carried by a single notch of the cord-carrier simultaneously and independently as set forth.

WILLIAM GOPPAGE.
